High Definition lenses enhance contrast by reducing the scattered blue light that causes objects to appear “flat” against backgrounds. Contrast is improved so objects appear more sharply defined. Colors are bright and vibrant. Glare is virtually eliminated, allowing your eyes to relax and see everything remarkably crisp and clear. The HD lens cuts through haze and glare for optimum visual clarity, even at a distance. Sharpens contrast while maintaining a natural, no-distorted color balance.
